Home-brew pseudo Doppler radio direction finding systems are typically based on discrete components. Much of the hardware complexity can be replaced with a software design, using minimal external components to the Raspberry Pi. This can dramatically lower the cost of implementation, provide additional signal processing capabilities, and provide remote control capabilities that permit the coordination of multiple units for instant triangulation.
We're going to use Big Blue Button for this meeting:
